The error "a patchresponse was monotone" about clmtrackr HOT 2 CLOSED

Hi,
the first error message about monotone patch responses is nothing to worry about, it's just for information. The second bug sounds like you tried to get the image data from a canvas before the image was loaded, see http://stackoverflow.com/questions/25492304/exception-floating-parameter-is-not-finite-canvas

Not sure if that bug is in clmtrackr or in your code, I'd have to see the page to be able to tell.

Hello

I guess that the camera was dark or white.
The error occurred.

a patchresponse was monotone, causing normalization to fail. Leaving it unchanged.

And later.

Uncaught TypeError: Failed to execute 'getImageData' on 'CanvasRenderingContext2D': float parameter 1 is non-finite.

sometimes the error happened.

when the error happened the camera can't detect later.

Could you tell me how to fix it?
Or is it bug of library?
